Hello Everyone, long time reader, first time poster here. Great site.
Last fall I bought a Daewoo Solar 035 excavator, somewhere around 2000ish vintage. Like everything I buy, it was neglected and broken, but it's coming together pretty well, fixing leaks, cutting out rust, fabbing new parts, etc.
It has a linkage operated "PTO" valve on the main valve block which operates it's hydraulic thumb, with what looks like an inline pressure relief valve that is tee'd right into the lines that go to the thumb cylinder. Right now, there is a crummy little foot pedal that operates the thumb, and I'd like to change that to a thumb switch style solenoid valve controlled by my joystick buttons.
I found a thread called
My main question is, how do I do the plumbing from the solenoid valve to the excavator in my case? Maybe I should say where do I get the P line, and where to send the T line? Wiring and plumbing to thumb and joysticks I think I've got figured out.
I'm not a great communicator, hopefully a few of you guys can see what I'm getting at.
Thanks guys,

I found a thread called
"What solenoid directional control valve for thumb."
Which answers about 95% of all of my questions, looking at uffex's PDFs he posted, etc. But, my machine does not have a pilot pressure controlled valve at the thumb ports like the original poster of that thread. My rig has mechanically actuated valves on travel, dozer, and what they call pto, which is my thumb. The other valves are pilot pressure controlled.My main question is, how do I do the plumbing from the solenoid valve to the excavator in my case?
